Abstract
Description
Technical Field
[0001] This utility model relates to the field of uncoiling device technology, and in particular to an uncoiling device for a fully hydraulic constant roller gap wide and thick plate leveling production line. Background Technology
[0002] The uncoiling device in a fully hydraulic constant-roll gap wide and thick plate leveling production line is a key component of the production line. It is responsible for uncoiling the wide and thick plate material and feeding it into the subsequent leveling process. The uncoiling device is mainly used to uncoil steel coils, especially wide and thick plate steel coils, and smoothly feed them into the leveling equipment for subsequent leveling treatment. It is the bridge connecting the raw materials and the leveling equipment, playing a vital role in the continuity and stability of the production line. The structure of the uncoiling device typically includes a frame, drum, transmission system, and control system.
[0003] Once an existing uncoiler is produced, the expansion and contraction range of its expansion and contraction drum is fixed. If the inner diameter of the steel coil exceeds the maximum expansion and contraction diameter of the uncoiler, the uncoiler will be unable to tighten the steel coil, and a larger diameter uncoiler needs to be purchased, which greatly increases the production cost.
[0004] Existing patent (publication number: CN217665499U) discloses an uncoiler diameter-increasing device, which includes two sets of diameter-increasing components symmetrically arranged on the uncoiler's expansion and contraction drum, and detachably connected to the sector-shaped blocks on the expansion and contraction drum. Each set of diameter-increasing components includes an increasing plate and a connecting component. The increasing plate is arc-shaped and detachably connected to the sector-shaped blocks via the connecting component. By symmetrically arranging two sets of diameter-increasing components on the uncoiler's expansion and contraction drum and detachably connecting them to the sector-shaped blocks, and by detachably connecting the increasing plate to the sector-shaped blocks via the connecting component, the maximum expansion and contraction diameter of the expansion and contraction drum is increased, expanding the applicability of the uncoiler and reducing production costs.
[0005] To address the aforementioned issues, existing patents have proposed solutions that enable detachable connection between the diameter-increasing plate and the sector block via connecting components, thereby increasing the maximum expansion diameter of the expansion and contraction drum and expanding the applicability of the uncoiler. However, in practical use, because this solution relies on the sector block to achieve the diameter-increasing effect, it still cannot effectively adapt to steel coils with different inner diameters, resulting in relatively poor practicality. Summary of the Invention

It eliminates the need to use a diameter-increasing plate with a fixed thickness for clamping and fixing, and ensures that steel coils with different inner walls can be clamped. It is highly practical and solves the problems mentioned in the background art.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution:
[0027] Please see Figures 1 to 4An uncoiling device for a fully hydraulic constant roller seam wide and thick plate leveling production line includes a device frame 1, a rotating roller 2 installed on the right side of the device frame 1, an adjustment mechanism for adjusting the clamping diameter inside the rotating roller 2, a drive mechanism for uncoiling the steel coil at one end of the rotating roller 2, and an auxiliary mechanism for supporting the device on the right side of the rotating roller 2.
[0028] The adjustment mechanism includes a stepper motor 3, which is fixed inside the rotating roller 2 by bolts. The power output shaft of the stepper motor 3 is fixed with a lead screw 31. A movable part 32 is slidably connected to the outer surface of the lead screw 31. Three hinge rods 33 are hinged to the outer surface of the movable part 32. Each of the three hinge rods 33 is hinged to a clamping plate 34. The left side of the clamping plate 34 is hinged to the outer surface of the rotating roller 2. A limit block 35 is fixed to one end of the clamping plate 34. A fixing plate 36, which is fixedly connected to the rotating roller 2, is connected to the left side of the limit block 35. A limiting groove 37, which is slidably connected to the limit block 35, is opened inside the fixing plate 36. The drive mechanism includes a worm gear 4, which is fixed to one end of the rotating roller 2. A worm 41 is meshed on the upper surface of the worm gear 4. A drive motor 42, which is bolted to the device frame 1, is fixed to the input end of the worm 41.
[0029] By adopting the above technical solution, before using the uncoiling device for the full hydraulic constant roller gap wide and thick plate leveling production line, the device frame 1 is first placed in a suitable position, and the steel coil is pushed into the outside of the rotating roller 2 using an external device. At this time, the stepper motor 3 is started to drive the lead screw 31 to rotate, which in turn drives the moving part 32 to move horizontally. With the cooperation of the hinge rod 33, the clamping plate 34 can move outward and contact the inner wall of the steel coil. And through the limiting block 35 set on the clamping plate 34, with the cooperation of the fixed plate 36 and the limiting groove 37, the direction of movement of the clamping plate 34 can be guaranteed. When the outer wall of the clamping plate 34 contacts the inner wall of the steel coil, the clamping and fixing function is achieved, which plays a stepless adjustment role. There is no need to use a diameter increasing plate with a fixed thickness for clamping and fixing, which can ensure the clamping of steel coils with different inner machines and has strong practicality.
[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the auxiliary mechanism includes a support frame 5, which is located on the right side of the rotating roller 2. The upper surface of the support frame 5 is rotatably connected to two support rollers 51 that are movably connected to the lead screw 31 via bearings. An mounting plate 52 is fixed to the upper end of the support frame 5. A fixing rod 53 is fixed vertically inside the mounting plate 52. A movable block 54 is slidably connected to the outer surface of the fixing rod 53. A spring 55 sleeved on the fixing rod 53 is abutted to the upper surface of the movable block 54. A guide roller 57 is connected to the left side of the movable block 54. A fixed bearing 56 embedded in the inner wall of the movable block 54 is sleeved at one end of the guide roller 57.
[0031] By adopting the above technical solution, the support frame 5 is moved to the end of the lead screw 31, so that the two support rollers 51 on the support frame 5 support and limit one end of the lead screw 31, thereby increasing the strength of the lead screw 31. The drive motor 42 drives the worm gear 41 to rotate, which in turn meshes with the worm wheel 4 to rotate, driving the rotating roller 2 to rotate and unwind the steel coil. Furthermore, the fixed rod 53 set in the mounting plate 52, under the elasticity of the spring 55, pushes the movable block 54 to move vertically, thereby driving the guide roller 57 to contact the outer wall of the steel coil, pressing and limiting the steel coil to prevent it from unwinding too quickly, ensuring the unwinding effect. In addition, the fixed bearing 56 allows the guide roller 57 to rotate, making it easy to use.
[0032] Working principle: Stepper motor 3 drives lead screw 31 to rotate, which in turn drives moving part 32 to move horizontally. With the cooperation of hinge rod 33, clamping plate 34 can move outward and contact the inner wall of steel coil. Through the limiting block 35 set on clamping plate 34, when the outer wall of clamping plate 34 contacts the inner wall of steel coil, the clamping and fixing function is achieved. After clamping, support frame 5 is moved to the end of lead screw 31, so that the two support rollers 51 on support frame 5 support and limit one end of lead screw 31. Drive motor 42 drives worm gear 41 to rotate, which in turn meshes with worm wheel 4 to rotate, driving rotating roller 2 to rotate and unwind steel coil. Through the fixing rod 53 set in mounting plate 52, under the action of spring 55, it will push moving block 54 to move vertically, which will drive guide roller 57 to contact the outer wall of steel coil and press and limit steel coil. The fixed bearing 56 set allows guide roller 57 to rotate.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
